JAMES B. BAILEY, OF WEST LIBERTY, OHIO, ASSIGNOR OF ONE-HALF TO i JAMESG. REDMOND, OF SAME PLACE.

ELEVATOR.

SFEGIFIGATION forming part of Letters Patent No. 468,756, dated February9, 1892.

Application filed July 81, 1891. Serial No. 401,276. (No model.)

To aZl whom it 72mg concern:

Be it known that 1, JAMES B. BAILEY, a citi- Zen of the United States,and a resident of \Vest Liberty, in the county of Logan and State ofOhio, have invented certain new and useful Improvements in Elevators;and I do declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference toletters of reference marked thereon, which form a part of thisspecification.

Figure 1 of the drawings is a front elevation, partly in section; andFig. 2 is a detail view.

My invention relates to certain improvements in door openingand closingdevices for elevators; and it consists in the novel construction andcombination of parts, as hereinafter described, and pointed out in theclaim.

In the accompanying drawings illustrating the invention, the letter Adesignates the shaft or well, and B the cage or car therein.

O represents the door .of the shaft, and which is shown as of the usualsliding form.

On each floor of the building, at one side of the shaft or well A, ishung the toothed or cog wheel D, having rigidly secured thereto an arma, provided with a wrist a, to which is connected one end of a rod E,the other end of which is connected to the door O at any suitable point,as at c.

H H represent two segments or racks carried by the cages or cars, onebelow and one above the floor thereof, and in position to engage thetoothed wheel D on opposite sides.

The operation of the parts is as follows: Upon the ascent of the car orcage the upper rack II will engage the teeth of wheel D just before thecar reaches the level of the floor, turning said wheel and, by means ofthe wrist and rod connection, sliding the door open as the floor isreached. As the carcontinues to ascend, the lower rack II will engagesaid wheel on the opposite side, turning it in the reverse direction andoperating to close said door. Upon the descent of the car the rack IIwill first engage the cogs to open the door, which will be closed by therack II as the car continues to descend. One or more small anti-frictionrollers h maybe placed under the lower end of the door to preventbinding when operated.

It is obvious that a swinging door might be employed, the point ofconnection therewith of the rod E being so located as to open and closeit by the operation of said rod.

Having described this invention, What I claim, and desire to secure byLetters Patent, 1s-

The door-operating device for elevators,

comprising the rotary toothed segments 10- .cated at the landings andhaving an arm ct rigidly secured thereto and provided with a wrist, anda rod connected at one end to said wrist and at its opposite end to thedoor or gate, in combination with the rack-bars carried by the ear, oneabove and one below its floor, and adapted to engage opposite portionsof said segments, substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.

JAMES B. BAILEY.
